Characters with a (*) i haven't used before, or have some other issues i'll discuss below. You can vote on multiple, so try to include a character without an astrisc.

Pharah - The poses for her would be somewhat limited due to her pubic region deforming when her legs are put in certain ways. I still think I could get a couple good poses though. Fixing it is a bit above my level (weight painting), but it's something I want to learn at some point.

Lara Croft - Don't plan on doing missionary or cowgirl again for the time being. But feel free to vote for her if there's some other pose that would fit your fancy.

The rest I haven't used. I'm under the impression that they're useable though. Should there be a major issue, i'll defer to second place.
